MoNaCo: More Natural and Complex Questions for Reasoning Across Dozens of Documents

Tomer WolfsonHarsh TrivediMor GevaReut Tsarfaty
2025
TACL

Automated agents, powered by Large language models (LLMs), are emerging as the go-to tool for querying information. However, evaluation benchmarks for LLM agents rarely feature natural questions… 

ScholarEval: Research Idea Evaluation Grounded in Literature

Automatic research with Large Language Models (LLMs) is rapidly gaining importance, driving the development of increasingly complex workflows involving multi-agent systems, planning, tool usage,… 

Aligning LLMs to Ask Good Questions A Case Study in Clinical Reasoning

Shuyue Stella LiJimin MunFaeze BrahmanMaarten Sap
2025
COLM

Large language models (LLMs) often fail to ask effective questions under uncertainty, making them unreliable in domains where proactive information-gathering is essential for decisionmaking. We… 

HAICOSYSTEM: An Ecosystem for Sandboxing Safety Risks in Human-AI Interactions

Xuhui ZhouHyunwoo KimFaeze BrahmanMaarten Sap
2025
COLM

AI agents are increasingly autonomous in their interactions with human users and tools, leading to increased interactional safety risks. We present HAICOSYSTEM, a framework examining AI agent safety… 

ParaPO: Aligning Language Models to Reduce Verbatim Reproduction of Pre-training Data

Tong ChenFaeze BrahmanJiacheng LiuHanna Hajishirzi
2025
COLM

Language models (LMs) can memorize and reproduce segments from their pretraining data verbatim even in non-adversarial settings, raising concerns about copyright, plagiarism, privacy, and…
